I had clamxav scan my user last night around 12am just for a test. I noticed that it dropped the percentage of cpu idle to around 20-30 which isn't good. I thought the scan would finish in a few hours so i didn't check my computer this morning but when i got home about 10 minutes ago it was still scanning. This means it was scanning for about 18 hours or so. The cpu was working at 30 % idle and it seems kinda hot my mac. There is a slight smell coming from the mac but maybe I'm being paranoid but i can smell it. Is running it that long bad for my mac. just a little worried now.
